i Y; KING, a citizeny of the 'UnitedStates'. residing at Bentonville,"`in` thefcounty vof Benton and State of Arkansas, have invented certain new and useful.'Irriprovements in Vents,

Vof which i the Jfollowing is la speciication,

especially designed and adapted foriise ink referencelbeing had to the accompanying drawings. Y

This `inventionrelates to certainimprove# ,ments 1n vents 'and has relatlon more partie-- ularly` to a device: 'of this general ycharacter connection withfia refrigeratorcar orjkin` dred rolling stock and it vis l anobjjecty of :the

invention tov provide a novel anduimplroved device of this general character whiclauto matically operates to permit theescape of gases and ,'vitiated air withina substantially sealed body.

Anotherjebjef "Ofi the invention' is to pil@- videa novelfa'nd improved device Aof this.

In order that my 'invention may( bef thefv betterl understood, I will' now proceed tof` describe the 'Same .with 'rference t. the, acl Companyingdm'wmgs,Whereim Figure l isf a view partly inV section and,

partly in elevation illustrating a vent conl structed in accordance with anl embodiment of my invention and in applied position;

v vlA'svis"particularlyillustrated in Figurel;

itfisuto be noted *that'thepcasingC andthe gooseneck 6 'are' of suchfdimensions as tojperj' 'mit the same Ito be positioned f belowY -`the running-'board -B j so kthat such vcasing` andl @is@necky WuijQlreriilo hinderen@ or 0b. structlon -to af; trainma'n or'otherwise offer means whereby vitiated air or gases risingl -from the load may readilyvescape to the atmosphere whereby a more e'ective preser-A los vation of theuload is permitted. Bypermit- I ting the gases or vitiated air to escape, it is assured that the entire interior of the car will have a maximum refrigeration as it is well-known that the warm air or gases Will rise and by permitting` such air or gases to escape the same will be readily replaced by the cold air.

The valve 7 as hereinbefore stated, is normally in its closed position but, when the car is in transit the. resultant vibrations or transit shocks` will cause the valve 7 at intermittent periods to be thrown into open position and during which periods the vitiated air or gases will escape.

When it is desired to positively close the flow through the tubular member or sleeve l, a plug 8 or the like is engaged with an en'd portion of the member or sleeve l and preferably the inner or inserted end, as isparticularly illustrated in Figure 3 of the accompanying drawings.

By the use of my improved vent the load within a refrigerator car and particularly in connection with berries and fruits, may be materially increased over the load which is now generally permitted yet with the increased load a more effective preservation is assured.

From the foregoing ldescription it is thought to be obvious that a vent constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention issus'ceptible of some change and modification with- -1 out departing from the principles and spirit thereof and for this reason I do not Wish to be understood as limiting` myself to the pref cise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

1. In combination with the roof of a refrigerator car, a tubular member disposed through such roof, a flanged collar engaged with the inserted end portion of the tubular member to provide means to secure the member to the inner surface of the roof, a casing threaded upon the outer end portion of the c tubular member and provided with a shoullder for contact withthe outer surface of the roof to provide additional means for maintaining the tubular member in applied position, 'said tubular member being in communication with the casing, a freely movable valve within the casing and normally closing the .flow through the tubular member but readily moving into open position incident to vibration of the carin transit, and a goose neck in communication with the casing and with the atmosphere.

2. In combination with the roof of a refrigerator car, a tubular member disposed through such roof, a flanged collar engaged with the inserted end portion of the tubular member to provide means to secure the member to the inner surface of the roof, a casing threaded upon the outer end portion of the tubular member and provided with arshoulder for contact with the outer surface of the roof to provide additional means for maintaining the tubular member in applied position, said tubular member being in communication with the casing, a freely movable' with the. inserted end portion of the tubularv member to provide means to secure the member to the inner surface of the roof, a casing threaded upon the outer end portion of the tubular member and' provided withr a shoulder for contact with the outer surface of the roof to provide additional means for maintaining the tubular member in applied position, said tubular member being in communication with the casing, `a freely movable valve within the casing and normally clos-` ing the flow through the tubular member but readily moving into open position incident to vibration of the car in transit, a goose neck in communication with the casing and with the atmosphere, and meansr coacting with the inserted end portion of the tubular member for closing flow therethrough, said goose neck communicating with the casing through the top at arpoint opposed to the tubular member'.

In testimony whereof I hereunto afiix my signature.
